What types of PTSD treatments have been studied? 

There are 550 studies of PTSD treatments in adults. These are randomized controlled trials--meaning, participants were assigned at random to an intervention group to test how effective a treatment is. 
Almost half of these studies are therapy trials (44% or 244 of the 550).
There are fewer, but still many, medication studies (19% or 102 of the 550).
  • Psychotherapy = therapy
  • Pharmacotherapy = medication
  • CIH = complementary and integrative health (such as meditation, yoga, etc.) 
The PTSD treatment studies were published between January 1, 1988 and April 1, 2024. Therapy continues to be the most commonly studied treatment. Over time, more studies have examined complementary and integrative (CIH) interventions. Another growing area of research is testing combination treatments, such as doing therapy and taking medications together to see if outcomes improve more than either treatment alone.
